DETACHABLE TOOL-HANDLE.

SPECIFICATION 'Orming part Of Letters Patent NO. 784,772, dated March14, 1905.

Application tiled April 11, 1904. Serial No. 202,571.

To LZ/Z U17/1,071@ t may con/cern:

Be it known that I, 1V1LLIAMASHERT, a citizen of the United States,residing at Des Moines, in the county of Polk and State of Iowa, haveinvented certain new and useful Improvements in Detachable Tool-Handles,of which the following is a specification.

The object of my invention is to provide a a tool and handle in whichthe handle may be readily, quickly, and easily attached to thev with myimproved handle applied thereto.l

Fig. 2 shows a longitudinal central sectional view of the tool and theadjacent portion of the handle. Fig. 3 shows a like view with the handleprojected farther through the tooleye, and Fig. L shows a transversesectional view through the center of the tool and the adjacent portionof the handle.

Referring to the accompanying drawings, I have used thereference-numeral 10 to indicate the tool. In the accompanying drawingsI have shown a miners pick as the tool to be applied to the handle, itbeing understood that the handle is designed to apply to any similartool. At the center of the tool is a handle-eye tapered from the lowerto the upper surface of the tool, said handle-eye being oblong in shape.Near the top of the tool I have formed in the side walls thereofadjoining the handle-eye two notches to receive a cross-piece 11. Thesenotches do not extend outwardly through the side walls of the tool. Theysimply `form a rest to receive the cross-piece 11, so that its top maybe flush with the top of the tool. The said cross-piece is provided witha central opening designed to receive a screwthreaded rod 12, having ahead 13, the said head capable of entering the cross-piece, so that itstop is iiush with the top of the crosspiece. Formed in the center of thehead 13 is an angular recess 14, designed to receive an angular wrenchby which the screw-threaded rod may be turned.

The reference-numeral 15 indicates the body portion of thehandle-socket. This body portion is preferably formed solid and may beof cast metal. Its exterior is tapered to accurately fit the handle-eyeof the tool. At its outer end is a transverse notch 16, designed toadmit the cross-piece 13 when the handlesocket is projected partlythrough the handle-eye of the tool. The outer surface of its lower endis tapered downwardly and inwardly and formed hollow to receive a woodenhandle 17, which may be secured to the socket by the bolt 18. In the endof the wooden handle I have provided an opening 19 to receive thescrew-threaded rod 12, as shown in Fig. 4.

In practical use it is only necessary to provide a single handle with alarge number of tools, and assuming that the tools used in connectionwith the handle were miners picks the metal of which the tool proper iscomposed must be a relatively high-grade steel and the only parts ofthis steel that are subjected to excessive use and wear are the points,and yet there must be a certain weight given to the combined tool andhandle to make the pick effective, and it is important in tools of thiskind that the weight be almost wholly contained within the tool proper.For this reason I provide the tool proper with a handle-eye ofrelatively large size, so that there is little steel in the tool itself.I then form the socket-body to lit the interior of the handle-eye andform the said socketbody solid and so arrange the socket-body that thesolid heavy portion thereof lies almost wholly within the handle-eye. Inorder to firmly secure the handle-socket in the tool, I place thecross-piece 11 in the shoulders provided for it at the sides of thehandle-eye, and I then pass the screw -threadcd bolt 1Q through theopening in the cross-piece and into and through the body portion ofhandlesocket, which is screw-threaded to receive the said rod. Then thevrod 12 is turned as far as possible, the handlesocket will be firmly maybe elevated out of the shoulders provided for it and turned to positionlongitudinally ot' the handle-eye, whereupon the tool may be detachedand a new one substituted. Assuming that the socket-body portion doesnot fit the handle-eye of the new tool in the same way as the tool whichis removed, then the operator may by turning the screw-threaded rod l2far enough draw the handle-socketbody portion 'farther up through thehandleeye until an accurate lit is obtained, as shown in Fig. 4L.

Obviously none of the parts of the attaching devices are exposed to wearor breakage and the major portion of the weight ot' the handle-socketbody is contained directly in line with the longitudinal center ot thetool, as required for effective work.

Having thus described my invention, what l claim, and desire to secureby Letters Patent ot' the United States therefor, is-

l. The combination with a tool having a handle-eye and also havingnotches adjacent to the upper end of the handle-eye, of a crosspieceresting in said notches and formed with a central opening, ahandle-socket having a body portion introduced into the handle-eye,

said body portion formed with a notch at its upper end to receive saidcross-piece and a screw-threaded rod passed through the crosspiece andseated in the socket.

2. The combination with a tool having' a handle-eye tapered from itslower to its upper end, ot' a cross-piece at the upper end ot' thehandle-eye resting on the tool-head, a handle-socket having a solid bodyportion tapered to iit the handle-eye and susceptible ot' projectingabove the top of a tool-head having a handle-eye'ot sutlicent size andformed with a notch to receive the cross-piece, and a screw-threaded rodmounted in the cross-piece and seated in the body portion otl thesocket.

3. The combination with a toolformed with a handle-eye tapered from itsupper to its lower end and also formed with notches in the sides ot' thetop portion of the tool adjacent to the handle-eye, otl a cross-piecerestingI in said notches and formed with a central opening, ahandle-socket formed with a solid body portion tapered to iit thehandle-eye and formed with a transverse notch at its upper end toreceive said cross-piece, a handle secured in the socket and a headedscrewthreaded rod passed through the cross-piece through the notch inthe top of the handlesocket and seated in the handle-socket, said rodformed with an angular opening in its head.
